I have a problem with 5.25.3 PicoLog software version. Often, when the PicoLog windows is minimized on the tray bar, the PicoLog icon disappears. To restart again the PicoLog windows, I have to do the following operation:

1) open the task manager2) kill the plw32.exe process3) double click on the plw32.exe file

When minimised the PicoLog software will go into the system tray at the bottom right. Check this area, including the hidden items section, for a blue PL icon. This is by design to prevent accidental closure of the software when recording.
